Abstract

For multi-section drainage facilities, it is important to develop operational measures based on maneuvering moving barriers. Maneuvering of moving barriers is a measure that carries out the flow of water from the upper reaches to the lower reaches at the required level, taking into accounts the design features and operational mode of the hydraulic regime of the drainage structure. The maneuvering mode in the flow of water from the discharge structures ensures the order of opening, phasing, and level of opening of these movable barriers. Hydraulic conditions are associated with the effective control of the hydraulic regime in the lower part of the drainage structure or the suppression of excess kinetic energy, the reversal of the flow, or the prevention of post-riser deformation processes. Creating conditions ensuring that the hydrotechnical and hydropower construction of the water transfer or discharge facility is adapted for use in conjunction with a hydropower plant, water intake, sluices, and flow control system.

Highlights

It is especially important to conduct targeted research aimed at the development of scientifically based calculation methods for quenching the kinetic energy of water flow in water discharge facilities, the selection of flow energy quenching structures, the elimination of water flow inversion [1-6]
In the form of an external hydraulic jump, the length of the contact area is longer than when descending along the bottom of the channel when the pounds are connected, and the excess kinetic energy is more attenuated at the connection along the bottom of the channel;
We study the hydraulic parameters and dynamics of the flow state at different water flows of the flow

Summary

Introduction

It is especially important to conduct targeted research aimed at the development of scientifically based calculation methods for quenching the kinetic energy of water flow in water discharge facilities, the selection of flow energy quenching structures, the elimination of water flow inversion [1-6]. One of the important tasks is to select design solutions for quenching the kinetic energy of water flow in water discharge facilities, to determine the hydrodynamic stresses of water flow to lower basin structures, to conduct new experimental research on water connection and discharge structures and to conduct scientifically based calculation methods [7-14].
